Looking at the above responses, you came HERE for expert advice? ROTFLMAO!
My useless opinion? For a huge number of economic reasons, I see serious downsizing of rigs in the next 10 years as people who are so ridiculously upside down realize that perhaps that 500K "investment" that is now worth 100K or less wasn't such a good idea.
In luxury digs, there is a small amount of room for upgrading infrastructure (emphasis on the "small" which is very likely to not be realized in a shrinking market) but as to the rank and file mid to low market private entities, there is practically no room and as to public properties, forget about the upgrades suggested by others here for 2 very important reasons: 1) There is no expansion land. 2) There is no money, and THAT money situation, friends, is where the discussion ends. Hopefully.
